Description
Technical field
The utility model relates to a kind of petroleum sleeve joint.
Background technology
Drilling technology in progress, to well casing require also more and more higher, specification and structure also more and more abundanter, the requirement of quality and efficiency is gone forward side by side.In prior art, when adopting joint to be coupled together by two petroleum casing pipes, usually can run into the different situation of caliber of two petroleum casing pipes, now, staff needs the joint matched with the caliber of petroleum casing pipe with two, is first connected with petroleum casing pipe, then is coupled together by two joints by middle transition pipe, on the one hand, lose time, affect productivity effect, on the other hand, because interface is more, there is the danger of leakage of oil; In addition, the petroleum sleeve joint used in prior art is often corroded very serious, has a strong impact on the application life of joint.The weak point that Here it is existing for prior art.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the deficiency existing for prior art, and a kind of technical scheme of petroleum sleeve joint is provided, use the utility model sleeve pipe identical for caliber can not only to be connected, fast different for caliber two sleeve pipes can also be connected, improve operating efficiency.
This programme is achieved by the following technical measures: a kind of petroleum sleeve joint, comprise the adapter sleeve matched with petroleum casing pipe, described adapter sleeve comprises outer sleeve, the first inner sleeve and two the second inner sleeves, described two the second inner sleeves are connected to the two ends of the first inner sleeve, the side of described first inner sleeve and the second inner sleeve is taper surface, this taper surface is provided with the internal thread matched with the external screw thread on petroleum casing pipe, in the cavity that described first inner sleeve, two the second inner sleeves and petroleum casing pipe are formed, is provided with airtight and watertight padding.
Further improvement of the utility model also has, and the two ends of described outer sleeve are provided with the gas thread matched with petroleum casing pipe.
Further improvement of the utility model also has, and the two ends of described outer sleeve are provided with the zigzag projection that petroleum casing pipe matches.
Further improvement of the utility model also has, and the end of described gas thread is arcuate structure.
Further improvement of the utility model also has, and the surface sections of described anticorrosive packing is reticulate pattern section form.
Further improvement of the utility model also has, and the taper surface of described first inner sleeve is equal with the cone angle of the taper surface of the second inner sleeve.
Technical characterstic of the present utility model and good effect are:
(1) in the utility model, described adapter sleeve comprises outer sleeve, first inner sleeve and two the second inner sleeves, described two the second inner sleeves are connected to the two ends of the first inner sleeve, the side of described first inner sleeve and the second inner sleeve is taper surface, this taper surface is provided with the internal thread matched with the external screw thread on petroleum casing pipe, during use, can optionally dismantle two the second inner sleeves, to adapt to the petroleum casing pipe of different tube diameters, for clamping connects between first inner sleeve and the second inner sleeve, easy accessibility, substantially increase operating efficiency, and joint sealing performance of the present utility model is good, use safety,
(2) in the utility model, airtight and watertight padding is provided with in the cavity that described first inner sleeve, two the second inner sleeves and petroleum casing pipe are formed, effectively decrease stress corrosion and the electrochemical corrosion of petroleum casing pipe and casing joint, extend life cycle, save a large amount of petroleum casing pipes and joint, thus reach the object this being adopted cost.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model detailed description of the invention.
In figure, 1 is outer sleeve, and 2 is the second inner sleeve, and 3 is the first inner sleeve, and 4 is airtight and watertight padding, and 6 is gas thread, and 7 is petroleum casing pipe, and 8 is internal thread.
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, a kind of petroleum sleeve joint, comprise the adapter sleeve matched with petroleum casing pipe 7, the two ends of described outer sleeve 1 are provided with the gas thread 6 matched with petroleum casing pipe 7, accordingly, petroleum casing pipe 7 also have gas thread 6, the end of gas thread 6 is arcuate structure, accordingly, petroleum casing pipe 7 arranges the pyramidal structure matched with arcuate structure, and pyramidal structure is engaged mutually with arcuate structure; Also can be provided with the zigzag projection that petroleum casing pipe 7 matches at the two ends of described outer sleeve 1, accordingly, petroleum casing pipe 7 be provided with the groove matched with projection.
Described adapter sleeve comprises outer sleeve 1, first inner sleeve 3 and two the second inner sleeves 2, described two the second inner sleeves 2 are connected to the two ends of the first inner sleeve 3, the side of described first inner sleeve 3 and the second inner sleeve 2 is taper surface, the taper surface of described first inner sleeve 3 is equal with the cone angle of the taper surface of the second inner sleeve 2, this taper surface is provided with the internal thread 8 matched with the external screw thread on petroleum casing pipe 7, described first inner sleeve 3, airtight and watertight padding 4 is provided with in the cavity that two the second inner sleeves 2 and petroleum casing pipe 7 are formed, the surface sections of described anticorrosive packing is reticulate pattern section form.
When not using the second sleeve or use two the second sleeves, be applicable to the connection between two identical petroleum casing pipes 7 of caliber, when using second sleeve, be applicable to the connection between two different petroleum casing pipes 7 of caliber.After filler is placed, after the first sleeve or the second sleeve are connected with petroleum casing pipe 7 screw thread 6, then outer sleeve 1 is fixed on petroleum casing pipe 7, namely completes the connection to two petroleum casing pipes 7.
By reference to the accompanying drawings the detailed description of the invention of utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
